Thanks for posting.
I used to take stats for my tennis partner's matches and he, mine. We used a sheet and just kept track of errors and winners off the forehand, backhand, backhand volley, forehand volley, overhead and backhand slice.
This is easy enough once you are familiar with the sheet.
What the scorekeepers do is more difficult because there is a lot more that is tracked in real time. Direction of serves, returners return groundstroke and also analysis of points. Such as number of games won when the server lost his first service point, number of games won when the server went to duece etc.

I use some applications that you can buy on Itunes Store: it's called Tennis Trakker Pro ;)

I looked it up. It looks good. I don't have an iPhone though. I have a palm pre and I like it.

I agree with the premise that recording an unforced error by statisticians is not as subjective as television commentators let on. The amount of unforced errors recorded in the sport has risen in the past twenty years largely because the players have been willing to sacrifice power for control.
I think you meant to say 'sacrifice control for power'.
